MD1711 High-Speed Integrated Ultrasound Driver IC Features General Description Drives Two Ultrasound Transducer Channels The MD1711 is a two-channel logic controller circuit with low-impedance MOSFET gate drivers. It is Generates a Five-Level Waveform intended to be used with external FETs as a five-level Drives 12 High-Voltage MOSFETs high-voltage and high-speed transmitter. The MD1711 2A Source-and-Sink Peak Currents is designed for medical ultrasound imaging Up to 20 MHz Output Frequency applications but can also be used for metal flaw 12 V/ns Slew Rate detection, NDT and for driving piezoelectric transducers. 3 ns Matched Delay Times Less than 40 dB Second Harmonic The MD1711 has two sets of control logic inputs, one for Channel A and one for Channel B. Each channel Two Separate Gate Drive Voltages consists of three pairs of MOSFET gate drivers. These 1.8V to 3.3V CMOS Logic Interface drivers are designed to match the drive requirements of the TC6320. One MD1711 drives six TC6320s. Each Applications driver consists of an N-channel and a P-channel MOSFET. They are designed to have the same Medical Ultrasound Imaging impedance and can provide peak currents of 2 amps.
